i have a radio/cassette in my clio at present. brought a 2nd hand radio/cd player with the code..i fitted the new one in and entered the code but everytime i did it kept coming up with CODE in my display! re-fitted the original one and entered the code and whallah it worked fine. I have spoken to guy i brought the new one from and he assures me that the code is correct! but as i say when i enter the code it will not fire up and remains with the word CODE in the display! logic states to me that the code for that unit is in-correct? am i right or wrong? HELP>.
